EPECIPICATION forming part of Letters Patent No. 301,690, dated July 8,188%.

Application filed March 7, 1854. (X0 model.) I

To 62:55 whom it may concern: I

Be it known that we, DANIEL J. Ilwrnson and CHARLES H, BIICHAEL, both ofMarshall, in the county of Clark and State of llllinois, have inventedcertain new and useful Improvements in Home Attachments, of which thefollowing is a specification.

Our invention relates to improvements on those devices employed for theconnection of IO the tug-clip or trace-ring to the hame.

In our application for patent, (Serial No. 116,242) filed on the 2d dayof January, 1884, we have shown an improved plate for attaclr ment tothe home, such plate having lugs, be-

tween which the trace clip or clevis is vertically adjustable.

Our present invention consists, first, in an improved form of pin forconnecting plate and tracecievis, the pin being formed with ridges orprojections passing through corresponding holes in the lugs of the plateand clevis, and retained to place by turning within its seat. The advantages of this construction are, its ready capacity for adjustment orremoval,

its great durability, and the impossibility of its being accidentaliydisplaced, resulting from itslocking into the trace'clcvis, and itscheapness in cost over those pins which are screw threaded to occupycorresponding screw-threaded'lugs on the attaching-plate.

The second part of our invention consists in a peculiariyformed piece,called by us herein a clev'is, for the connection of the trace tug orring to the attaching or hame plate. This piece is made of U shape, withholes through both of its arms for the passage of the pin. These holesare of shape to re ceive the ridges or projections of the pin, so thatwhen the elevis is held back under the 40 strain otthc trace theprojections of the pin will be turned past their notches in the lugs ofthe attaching-plate, and the pin thus held from accidental removal. Aclevis formed connection of this sort is far superior to ahook, becauseof its much greater strength, of the distribution thereby of thcstrainmore evenly over the whole length of the pin, and of its capacity ofattachment to either leatherto g harness or trace'chain harness. Thehook line 8 3, Fig. 1.

l is the attaching'plate, fixed to the home by rivet-s, screws, orotherwise, and preferably having integrally cast ln 2 for the breastrim.

3 are lugs formed on plate 1 in vertical series, and having verticalholes or seats for a pin, 4. The pin t has ridges or projections 5 alongone side, which pass through corrcsponding notches or recesses, 6,.inthe'lugs when the pin is being inserted or removed. Bet-ween such ridgesthe pin is round so that when down to its scat it may be turned, and 7thus locked against upward motion. A head,

7, on the pin is provided for convenience of handling.

8 is the improved clcvis formed piece for the attachment of the tracetug or ring. Its two arms embrace the pin a above and below one of thelugs 3, the holes thcrcthrough being mode of shape to receive the rigidportion of the pin, so that when the clevis'is turned into the posit-ionshown in Fig. 1 the pin will turn with it, and be thus locked in placeso long as there is strain on the trace. The pin and clcvis turningfreely together, great flexibility is provided in the attachment, andwear on the harness thus avoided. The go clevis clasping the pin aboveand below one of the lugs, it is obvious that strain on the pin will beevenly distributed, no matter what the position of adjustment of theclevis.

Having thus described our invention, what 5 we claim as new therein, anddesire to secure by Letters Patent, is-

1. The combination of a hams-plate having two or more lugs with verticalholes or seats, 2. The com.bination,with thehame-platehav- 10substantially of the form described, a pin having lugs 3 and pin 4:, ofthe clevis-formed tug ingcomple'mentary lugs or projections at inor loopfor the attachment of the trace clip or terv'als, and a clevis or hookhaving similar I ring, constructed substantially as set forth.

5 holes all 'of said parts being so arranged as DANIEL J. DAVIDSON.
